Hypothesis
What is the evolutionary origin of the hybrid plant pathogen Verticillium longisporum?
Conclusion
Verticillium longisporum is a hybrid that originated from three different parental species and has an expanded host range.
Supporting Evidence
- Phylogenetic analyses confirmed that V. longisporum is diploid and originated from three different parental species.
- All hybrids shared a common parent, species A1, that hybridized with species D1 and V. dahliae.
- V. longisporum has larger conidia than any other species of Verticillium and is more virulent on oilseed rape.
Takeaway
Scientists studied a plant disease caused by a fungus called Verticillium longisporum, which is a hybrid from three different parent species and can infect many plants.
Methodology
Phylogenetic analyses were conducted using 203 isolates of Verticillium longisporum and related species, focusing on seven nuclear loci.
Limitations
The study does not identify the exact origins of the unknown parental species A1 and D1.
